Orion is rolling out from Kennedy Space Center to Cape Canaveral Air Force Station.

Weather conditions Monday night forced the space agency to delay rolling out the test capsule. The rollout has been rescheduled for 8:30 p.m.

The rocket is moving from the Launch Abort System Facility at the Kennedy Space Center to its launch pad at Cape Canaveral Air Force Station's Space Launch Complex 37. The trip takes about six hours.

NASA has targeted Dec. 4 for the first test flight of Orion.

Tickets for launch viewing at the Kennedy Space Center Visitor Complex are available online. Admission is $50 for adults and $40 for children. Launch transportation costs an additional $20 per person.

The unmanned test will take the spacecraft 3,600 miles above Earth on a more than four-hour flight to test many of the systems critical for future human missions into deep space.

After two orbits and 60,000 miles, NASA said Orion will re-enter Earth's atmosphere at almost 20,000 mph before its parachute system deploys to slow the spacecraft for a splashdown in the Pacific Ocean.

On future missions, the Orion spacecraft will help carry astronauts farther into the solar system than ever before, including to an asteroid and Mars.
